ALEXANDER ,HANGO, or PORTLAND, ormeon.

AIR-REGULATOR FOR AUTOMOBILES.

I T all 207mm it my concern:

Be it known that-I, ALEXANDER HANeo, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented a new and useful Air-Regulator for Automobiles, of which the following is a specification.

My invention relates to improvements in air regulators for automobiles, in which bypass valves are inserted in the carbureter air intake pipe.

The objects of myinvention are:

First, to admit to the carbureter air of a temperature best adapted for efiicient combustion.

Second, to provide an air regulator whichis accessible from the dash board.

I attain these objects with the mechanism illustrated in the accompanying drawing, in which- Figure I is an elevation of my apparatus as it appears when attached to an automobile.

'Fig. II is an end view of the air intake pipe showing the by-pass valves.

Fig. III is a fragmentary view of the dash board showing the lever mechanism.

Similar numerals refer to similar parts throughout the several views.

In a majority of the present-day automobiles the air intake pipe 1 for the carbureter 2 is connected to the exhaust 3 in order to preheat the air; but the instructions are that this pipe should be removed on hot days. This removal and re-attachment entails labor, and without the air intake pipe difliculty in starting the cold engine is often experienced. With my air regulator these evils are avoided. The air intake pipe can remain in place at alltimes, yet hot or cold air can be obtained by pressing a lever on the dash board.

For this purpose a hole 4 is cut in the pipe 1, and the hole closed by a cover 5 which is simply a curved plate fitting tightly over the hole. This cover is attached to the arm 6 of a suitably shaped bell crank, and as fulcrum for the bell crank a pin 7 is used, which latter. extends through the air intake pipe, and carries a damper 8 within the pipe, and a wire spring 9 at the pro ecting end. The damper is set to occupy an'open posi, tion when the cover closes the hole, said position being normally enforced by the wire spring. From the arm 10 of the bell crank goes a link rod 11 through the slot 12 of the Specification of Letters Patent.

dash board 13 and attaches to the lever 14:, which latter is fulcrumed to a bracket 15 on the dash board. When set for hot air the lever 14 occupies the position shown by the full lines on Fig, III. By pressing on the handle part of said lever the latter is caused to rotate in the direction of the arrow 16, bringing the handle part to rest against the dash board, and pulling the link rod up to the position shown in the dotted lines. The same position is shown in Fig. I, illustrating further how the hole 4 has thereby been uncovered. The damper 8 has at the same time barred the admission of hot air. Pressing on the lever in the direction of the arrow 17 permits the spring 9 to assert its tendency to return cover 5 and damper 8 to their normal positions.

Not even a new slot in the dash board needs to be cut, since the slot 12 which takes in the carbureter adjusting rod 18 will also accommodate the link rod 11.

Having thus described my invention, it will be seen that my objects have been accomplished, and, though I have shown the preferred form of construction, I'reserve to myself the right to make minor changes, providing I do not contravene the spirit and principle of my invention.

claim:

1. A carbureter, an air intake pipe for the carbureter, a damper in the intake pipe capable of opening or closing the passage through said intake pipe, a hole in the side of the intake pipe between the damper and carbureter, a cover on the outside of the intake pipe to close the hole, said cover being connected with the damper and operating in unison therewith, and means to actuate the damper and cover from the dash board of an automobile.

2. A carbureter, an air intake pipe for the carbureter, a pin extending transversely through the intake pipe, a damper mounted rigidly on the pin, ahole in the wall of the intake pipe between the damper and carbudamper and earbureter, a bell crank at one end of the pin, a Wire spring at the other end or the pin to hold the damper in open position, a cover for said hole affixed to one arm of the bell crank, a link rod attached to the other arm of the bell crank, said link rod extending to the dash board of an automobile, and a lever pivotally secured to the dash board and engaging the link rod to actuate the bell crank and retain the damper 10 Signed by me at Portland, Oregon, this 15 10th day of September, 1920.
